Mark, thanks for the reply. Dr Leddy analysis was that he does not think it is related to my neck. Also, it's not just lifting weights, but essentially doing anything physical, for more than a short period of time. That would include walking up a steep hill for ten minutes ,or weeding my garden for 30 minutes.

With regards to the sleep, something is definitely going on during sleep. Even without exercise, I've suspected something isn't right. I'll buy that censor, and see how the results turn out.

What is worrysome is that I have made ZERO improvements in my ability to work out. You would think over two years, maybe I would make small improvements, but there has been none whatsoever.
